Wikipedia: MofongoMofongo is a popular dish generally made with fried plantains or, less commonly, yuca and breadfruit. The dish is part of various Caribbean cuisines including Cuban cuisine (where it is known as fufu), Dominican cuisine and Puerto Rican Cuisine.

Description
Mofongo is generally made from fried green plantains, although fried yuca or breadfruit are possible, which is mashed and seasoned with broth, garlic, olive oil, and pork cracklings or bits of bacon. It is often filled with vegetables, chicken, crab, shrimp, or beef and is often served with fried meat and chicken broth soup. Mofongo relleno, is the Dominican Republic version; it is stuffed with stewed beef, chicken or seafood poured and topped with stewed sauce.

Origins
A Dominican cookbook author says that mofongo in Dominican cuisine can be traced back to Puerto Rico but scholarship indicates the dish is ultimately of African origin and is a variant of a dish called “fufu” which is made from various starchy vegetables and was introduced to the Caribbean by Africans in the Spanish New World colonies such as the Dominican Republic, Cuba, and parts of Puerto Rico. But unlike mofongo where the unripened plantains are first fried, then mashed with broth and olive oil, fufu is made of either green or semi-ripe plantain boiled then mashed.

...they can always be found in the cheap little restaurants on the city’s Puerto Rican streets, along with a few other things like salcocho or the dish called mofongo, which is made on a base of mashed plantains and pork cracklings.

The PUERTO RICAN MARKET on Park Avenue between111th and 116th Streets is, particularly on a sunny Saturday, a social center for gossiping and people-watching under pink clouds or petticoats hanging above store fronts, and for ambling conversationally among the inside stalls of tomatoes, dasheen, plantains, sizzling pastelillos and mofongo, friezes of corsets and nightgowns, bristling mounds of hair curlers and plastic ornaments.

Mofongo has been jocularly described as “a Puerto Rican matzoh ball.” It consists of mashed roasted plantain, combined with bacon and other spices and rolled into a ball. (it goes well with chicken soup.)

29 November 1978, New York (NY) Times, “THe Good Kitchens of Old San Juan” by Craig Claiborne, pg. C8:
At the Fuentes we dined on a fine platter of roast pig with crisp, brittle, nonfatty roast skin, tender, succulent morsels of roast meat and one of the island’s foremost specialties, mofongo, a curiously appealing mound of mashed fried plantains with pork cracklings, long-cooked pork skin that has a nutty flavor and an irresistable crisp richness.

Complementing these foods were a platter of hot, grilled, slightly spicy blood sausages and caldo, or rich broth made of chicken and containing meaty pieces of the bird. The mofongo gains character when dipped into the caldo before eating.

We’re talking empanadilla turnovers with truffle mojito sauce, risotto with chicharron (pork cracklings) and a makeover of the beloved local dish, mofongo — a Puerto Rican matzoh ball made from green plantains and pork. Benet tops his mofongo with a fat shrimp and lavishes it with saffron broth.
